You can jump to a symbol by using the -f <symbol> option on the Source Insight command line when you start Source Insight.
For example:
insight3 -f myfunc
This will position to the symbol named “myfunc”.
You can also simply give the name of the symbol on the command line without a special command option, as though it were a file name. In this case, Source Insight will try to determine whether the symbol you specified is either a file, or a parsed symbol. You can list as many symbols on the command line as you like, just as with file names.
For example:
insight3 myfunc fcb init
This will open all files where the symbols “myfunc”, “fcb”, and “init” are located. See also “Command Line Syntax”.
